HBO Go has officially landed, earlier than expected! As a quick refresher, if you're an HBO subscriber you'll be able to watch every episode of every season of The Sopranos, The Wire, Boardwalk Empire, Curb Your Enthusiasm, Rome, that vampire silliness, all on iOS or Android.

It's a treasure trove of not TV, but—for now—it's only available if your cable provider allows it. So congrats, AT&T, Charter, Cox, DirecTV, Dish, SuddenLink, Verizon, and Xfinity subscribers! You're lucky in a way that TimeWarner folks may never be. [Android Market, iTunes]
